Limp Stillen Supercharger dtc p1239

NissanTracker

So I have been fighting the p0300 and p1239 code since I ever installed the kit(2 years ago). I have an 07 HR nismo and last night the p1239 came back. I even have the update stillen cables. Was this ever resolved? I'm going crazy... still can't figure it out.

I never had a single problem with the z when it was N/A. Low miles and ran like a champ. Installed the charger, and gremlins. I get the p0300 only when it's cold out.... which is strange. the p1239 comes out of no-where. Last time I got this was last year.

I added extra shields at the filters,
Boost leak/ Vacuum leak tested,
installed a catch can
replaced spark plugs
re-tuned countless times for idle.

Thanks
